Elastic failure of a material occurs, when the tensile stress equals yield strength, yield point or the elastic limit. Also, the elastic failure occurs according to maximum strain theory, when the maximum tensile strain equals (where, ζ = yield strength and E = modulus of elasticity) ?
Correct answer: C. ζ/E
- A. E
- B. ζ
- C. ζ/E
- D. E/ζ
Explanation
In the elastic range, strain equals stress divided by Young’s modulus, so the yield strain is ζ/E. The alternatives ζ and E are stress and modulus quantities, not strain.
